Waterloo Handedness Questionnaire: Cross-Cultural Adaptation and Psychometric Properties of the Arabic Version.
Saleh M Aloraini
PMID 36304079WHAT IT FOUND
The Arabic Waterloo Handedness Questionnaire scored hand preference consistently when adults repeated it one week apart.
It can help PTs and OTs document handedness in Arabic-speaking adults, but it was not tested in disabled or stroke patients.
Key findings
01Adults' scores on the Arabic Waterloo Handedness Questionnaire were very stable when they repeated it one week apart, and the items hung together well.
02The questionnaire score matched the simple question about which hand is used for writing.
03The items worked mainly as one handedness score rather than separate subscales.

What it does not show
Participants were adult non-disabled Arabic speakers, so the questionnaire was not tested in stroke or rehabilitation patients despite the paper's rationale for rehabilitation use. All participants were from Saudi Arabia, and the translation used modern standard Arabic without local dialects, so understanding in other Arabic-speaking groups may vary. The retest period was only one week, so longer-term stability was not examined. The measure is self-reported hand preference, not an observed performance of hand use.
The easy way to misread this
Do not assume this questionnaire is validated for people after stroke or other disabilities. It was tested only in adult non-disabled Arabic speakers, so its scores in rehabilitation patients still need checking.
